Detailed Description

Represents a SNAP frame.

Note that this PDU contains the 802.3 LLC structure + SNAP frame. So far only unnumbered information structure is supported.

Constructor & Destructor Documentation

Tins::SNAP::SNAP	(	const uint8_t *	buffer,
		uint32_t	total_sz
	)

Constructs a SNAP object from a buffer and adds all identifiable PDUs found in the buffer as children of this one.

If the next PDU is not recognized, then a RawPDU is used.

If there is not enough size for a SNAP header in the buffer, a malformed_packet exception is thrown.

Parameters

buffer	The buffer from which this PDU will be constructed.
total_sz	The total size of the buffer.
